^ -This invention relates to'means for removing broken axles or the'like from their housings.vr` Y An object of this invention` is to provide means which may be inserted in a hollow or elongated tubularhousing for removing broken axles or other members from the houslngi A further object of this invention isfto provide a clamping device of this kind which is so constructed that it can be readily clamped about an article disposed within a tubular element for removing the article.

A-still further object of this invention is to provide a device of this kind which is eX- ceedingly simple in construction so that the device may be readily and cheaply manufactured.

The above and various other objects and advantages of this invention will in part be described in and in part b e understood from the following detailed description of the present preferred embodiment, the same being illustrated in the accompanying drawing, wherein Figure 1 is a. fragmentary longitudinal section partly in detail of a device constructed according to the preferred embodiment of this invention;

Figure 2 is a fragmentary detail side elevation of the device, and

Figure 3 is a sectional View partly in detail taken on the line 3-3 of Figure 1.

Referring to the drawing wherein like numerals of reference designate corresponding parts throughout the several views, the numeral 10 designates generally an elongated bar or shaft which is provided with a threaded portion 11 extending inwardly from one end thereof, and the numeral 12 designates a sleeve or tubular element which is loosely mounted about the periphery of the bar or rod 10, and which threadably engages the threads 11 so that rotation of the sleeve or Y tube 12 will move the tube longitudinally of i931. serial No. 551,257.

positionand the outer surface of these arms 14 is alsoprovided with threadsforming a continuation of the threads 11 so that lonfritudinal movement of the sleeve 312 will force the arms 14 one toward the other into clamp- 55 ing position. The outer ends of these arms 14 are bent inwardly, as at 15, Asoas to provide clamping members which have a pair ofprongs 16 formed therewith, these prongs being of V-shaped construction so as to readily engage` about thevperiphery of a round object in the form of a shaft or the like.

In normal position, these clamping members 15 are disposed away from each other so that the end of a shaft or other object may be readily inserted between these clamping members 15 and upon longitudinal movement of the sleeve 12, the arms 14 will be drawn together and coactively the clamping members 15 will be drawn toward each other and' 70 into engagement with the object disposed therebetween.A f' f Preferably, the prongs 16 are suitably hardened or tempered so that the points' of the prongs will readily grip a. metal object and firmly holdthe object therebetween. A sleeve operating member or lever 17, which has a bifurcated end portion 18 and alined lugs 19 is mounted in alined apertures 2O disposed in the sleeve 12 adjacent the'inner'end 80" thereof. Preferably, A the `bifurcated portion 18 of the sleeveoperating member 17 is bent angularly with respectl to the longitudinal axis of the body of the operating member 17 so that this operating member canbereadily pressuremay be applied for pulling'the ar- 5l ticle out of the housingy from which the shaft or other element is being withdrawn. If-def sired, the bar 10 may be of hollowtconstruction so as to make the rkdevice relatively'lig'ht in weight and also to facilitate the vconstrue:4 ,100

so that the clamping arms 14'will be in a.

position to readily be inserted into the desired housing or element vfrom which the ar- Y ticle is adapted to be removed and the clam-V v the following claims.

ing members 15 will be disposed apart su ciently that they may be inserted about the article within the housingV or other hollowv element. When the prongs 16 are disposed about the shaft or other element, the sleevel 12 may be rotated by means of the sleeve operating member 17, thereby movingthe sleeve 12 inwardly of the housing andzforcing the `divergent `arms 14 inwardly andco-` activelyclamping the clamping elements 15 about the shaft or other article. When the clamping members 15 aretightly engaged with the shaft orl article, the entire Vdevice maybe pulled outwardly of. the housing either by manually withdrawing the device, or a cable or other element maybe attach-ed to the inner member 10 in the aperture 13 and the desired pressure applied thereto so as to pull thershaft from the housing. s

It is,` of course, understood that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention :without departing from the spirit thereof, such changes and modificaf tionsbeing restricted only by the scope of I claim Y Y 1. A puller of the character described comprising divergent opposed clamping arms connected together at one end, threads formed on the outersurface of each of said arms, a threaded tubular element engaging the threaded portions of each of said arms where by upon rotation of said tubular element the armswill be drawnonetoward lanother for clamping an article therebetween, kand means for rotating said tubular element. y' 2. A puller ofthe character described coinprising divergent yieldable opposed clamping armssecured together at one end thereof, an elongated round element formed with the inner ends of said arms, threads carried by the outer surface of` said arms, a tightf ening member engaging the threads of said arms and adapted upon rotation thereof in f one direction to force said arms inwardly one toward another whereby to releasably clamp -an article therebetweem'and an operating member swingab'ly carried by said tightening member. 1

3. A puller of the character described comprising pairs of divergent clamping arms, an elongated bar formed withthe inner end of each'arm, atubular member disposed about said bar and having a threaded outer end porl.tion engaging the threads on said arms, and

operating means carried by said tubular member whereby to rotate said tubular mem-l ber for movement of said arms into clamping or released position.
